This is my presentation on principles of multimedia and contiguity for EDTECH 513 - Multimedia at Boise State University, Summer 2009.

1. Teaching Multimedia and Contiguity Principles Using Static Multimedia EDTECH 513: Summer Semester 2009 Robert Kilner

4. An Example of Good Use of Multimedia This is a good use of multimedia because it includes both text and graphics to go along with the text. The text and graphics support learning as they provide introductions to each section. These are called explanative graphics. Most of the graphics can be clicked on to enter various other parts of the site.

5. An Example of Poor Use of Multimedia This site is a poor example as it only includes links with no descriptions and graphics to support the text. Even the text does nothing in the way of supporting learning.

6. Another Example of a Poor Use of Multimedia This AT&T site from Canada is a poor use of multimedia since there are entirely too many “Decorative” graphics. That is, graphics that do not add to the learning process.

8. Different Types of Graphics and Their Uses A video showing two effective sales approaches. An animation showing genes passing from parents to offspring. Transformational, Interpretive Guidelines that result in completion of a task; cause-and-effect relationships Principle An animated illustration of how to use a spreadsheet. A diagram with arrows showing how to install a printer cable. Transformational A series of steps resulting in completion of a task Procedure Animations of how the heart pumps Still diagrams to illustrate how a bicycle pump works. An animation showing how a virus invades a cell. Transformational Interpretive Relational A description of how something works Process A tree diagram of biological species. Three excel formulas to illustrate formatting rules Representational Organizational Interpretive Groups of objects, events or symbols designated by a single name Concepts A screen capture of a spreadsheet. A table of parts’ names and specifications Representational, Organizational Unique and isolated information such as specific application screens, forms, or product data Facts Example Useful Graphic Types Description Content Type

11. An Example of Poor Use of Continuity The picture above shows directions on how to assemble Disney’s “Wall-E.” However, there are no instructions whatsoever, so the reader is left to try to figure it out for themselves, without any guide to lead them or help them troubleshoot.

12. Another Example of a Poor Use of Contiguity Here, the text does not match the graphics, therefore, the principle of contiguity is violated.
